BRICK-KILN.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application led March 26, 1914. Serial No. 827,455.

'0 all whom it may concern Be it known that I, BAPTISTE F. CANA- VERA, a citizen of the United States, residing at Nokomis, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Brick-Kilns; and .I do declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to improvements in brick kilns and the primary object of the same is to provide a kiln of the character described which will quickly and effectually burn the bricks placed therein and will produce a practical perfect article.

A secondary o, ject is to provide a simple arrangement of flues whereby the smoke and Hames from the res within the kiln iiiay be readily controlled.

With the above objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein? Figure 1 is a of my improved kiln; and Fig. 2 is a transverse section on the line 2-2 of Fig. 1. Fig. 3 is a detail vertical section showing certain of the parts, illustrated in Fig. .2, on an enlarged scale.

In the accompanying drawings, I have shown my improved kiln as comprising a continuous outer wall v1, a continuous inner wall 2 disposed within said wall 1 and eX- tending longitudinally7 tliereof, and a continuous arch 3 connecting the outer and inner walls as clearly shown in Fi 2.

The outer wall 1 is formed of inner and outer continuous walls 5 and 4 which are connected by transverse partitions 6 while the inner wall 2 comprises outer and inner walls 7 and 8 which are connected by transverse partitions 9. The compartments thus formed between the upright ortionsof the walls 1 and 2 are filled wit sand as indicated at 10. As clearly shown in Fig. 2 the sand also extends over the continuous arch 3 and forms an effectual insulator wherever it is employed. The outer portion 4 of the wall 1 is preferably inclined inwardlyfrom its loircr to its upper end and, at suitable intervals, arches 11 connect certain of the partitions 6, portions of the outer and inner elements of the wall `1 being cut away at the plan view partly in section ends of said arches for the purpose of providing door openings by means of which access may be had to the space between the walls 1 and 2 and beneath the continuous arch 3, said space forming a brick compartment 1 2 into which the bricks are placed for the purpose of burning.

The space between the upright portions 8 of theinner -wall 2 provides a smoke Hue 13 which is closed at its upper end by a longitudinal arch 14, the latter being broken near. its center to allow the flue 13 to communicate with a suitable smoke stack or chimney 15. At suitably spaced intervals, a'plurality of down draft flues 16, are provided, said lues extending transversely beneath the bottom 17 of the compartment 12, and having their inner ends curved upwardly and registering with upright openings 18 formed in a longitudinal filling wall 18a which is inclosed by the contacts with the lower portion of the inner continuous wall 2, said openings 18 discharging into the longitudinal smoke flue 13. The outer ends of the flues 16 curve upwardly and inwardly as indicated at 19 and communicate with the compartment 12 directly above its bottom 17. In addition to the flues 16. a plurality of upwardly converging up draft fues 20 are provided, said fiues leading through the upper poi-tion of the wall 2 substantially at the juncture of the arch 3 therewith, the discharge ends of said up draft flues being located directly above the filling wall 18f. Each flue 16 is-provided with a damper 21 while each flue 20 is provided with a damper 22, said dampers being provided with operating rods 23 which project through suitable openings in the arch 14. and lare in position to be operated by a. person standing upon the top of the kiln.

A suitable roof R may be supported in any suitable manner above the kiln and independent roofs 1' may be employed `over the door openings into the interior of the kiln. The roofs R and r are referably supported upon posts P and p andJ by opposite end walls W which are provided with door openings O.

In the operation of the device, the bricks to be burned are stacked within the compartment 12, suitable openings being left near the bottom 'of the piles of brick for the purpose of accommodating the lires. The desired quantity of brick is thus stacked in said compartment and upon the completion of this process, the res are built in the various openings left therefor and the dampers 22 of the flues 20 are openedto allow said fires to get an upward draft while the damper's 21 of the flues 16 are closed. The dampers are left in the above positions until the brick within the kiln has been heated to a predetermined degree whereupon, the dampers 22 are closed and the dampers 21 are opened. 'This action, although directing the flames and smoke downwardly, will cause terrific heat to be entrapped in the compartment 12. This heat will raise the temperature of the bricks being burned, to such a high extent that coal may now be fed through openings 24 which communicate with the interior of the brick compartment 12 and said coal will. immediately gasify and be consumed by the flames within the kiln.

By the specific positioning of the iues 16 and 20 and their dampers, it will readily be seen that the bricks may be heated to a high temperature by the temporary fires -which are built in the kiln and that the tendency of the heat and smoke to rise, is catered to. 1When however, the temperature of said bricks has risen suiiiciently, the dampers may be operated as above described, and when coal is fed through the openings 24, the major part of combustion will occur in the top of the continuous compartment 12 and since the heat cannot rise it will be drawn downwardly through the pile of bricks and will' be discharged through the lower flue 16 and intothe main flues 13 from which it will escape through the chimney 15. The temporary lires are no longer needed after the process of feeding fuel through the openings 24 is commenced and they may be allowed to die. l consider the positioningof the fiues 20, a very important feature of 'my invention since, as before stated, the tendency of the flames and smoke to rise, is catered to thus giving the temporary fires a great amount of draft which causes them to burn fiercely and quickly heat the bricks to the temperature at which they will gasify the fuel fed to them through the openings 24.V

From the foregoing description, taken in connection with the accompanying rawings, the construction and operation of the autres kiln will be readily understood without requiring a more extended explanation.

Various changes as to the form and minor details may be made but it is essential that the flues 15 and 20 retain the approximate relative position herein shown and described.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is v A brick kiln comprising an outer continuous 'wall having two parallel longitudinal side portions and end portions uniting the same, said wall having a plurality of door openings, an inner continuous wall having a pair of longitudinal side portions and end portions uniting the saine, said inner wall lying parallel tothe outer wall, a continuous arch connected at its outer edge to the top of the outer wall and at its inner edge to the outer edge of the inner wall, a single longitudinal arch connected at its longitudinal edges and at its ends to the inner upper edges of the inner wall, a longitudinal filling wall inclosed in the lower-'portion of the inneri wall, said filling wall coacting with the longitudinal arch to provide a longitudinal flue and having a plurality of longitudinally spaced upright openings, horizontal down draft smokey flues extending transversely beneath the bottom of the brick compartment existing between the inner and outer walls, the inner ends of said down draft flues registering with the openings in the filling wall and their outer ends communicating with said brick compartment directly above its bottom, upwardly converging vup draft smoke fiues formed through the inner continuous wall at points substantially at its juncture with the continuous arch, said up draft flues discharging at their upper ends into the main smoke flue, a stack rising from ysaid main flue, dempers controlling said up and down draft flues, and fuelfeeding ypassages formed through said continuous arch.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
